Other GK12 Sites
If you're interested in NSF DGE activities and would like to find out more about the GK12 program, the American Association for the Advancement of Science's central hub is a good place to begin.

There are several long-standing projects of note, including Larry Johnson's Partnership for Environmental Education and Rural Health at Texas A&M, Project Fulcrum at the University of Nebraska - Lincoln, and San Francisco State University's Science Education Partnership & Assessment Lab.

A program that mirrors our goals and objectives is the University of Illinois - Urbana-Champaign's project that seeks to integrate modeling and scientific visualization into math and science education.
